H6: Diario de un asesino / H6: Diary of a Serial Killer (2005) DVD9

When Antonio Frau is freed from 25 years of prison for killing his girlfriend in a fit of rage, he learns that he's inherited a large and grimy brothel. His sick mind interprets this as a sign from god that his purpose in life is to cleanse the world of the "undesirables", mainly drug addicts and prostitutes.
Antonio transforms Room 6 into his very own torture chamber--keeping it hidden from his new wife Francisca. Inside these plastic-covered walls he'll not only murder his victims (who're kept tied down on a table spread-eagle until he chainsaws them into chunks) but "purify" them before they die (which he does by starving them and dousing them in his own urine). As part of the process, Antonio keeps a meticulous diary outlining his every move and takes copious amounts of Polaroid photos of his victims before (and after) they die.
